useListController
useListController
contains the headless logic of the <List>
component. It’s useful to create a custom List view. It’s also the base hook when building a custom view with another UI kit than Material UI.
useListController
reads the list parameters from the URL, calls dataProvider.getList()
, prepares callbacks for modifying the pagination, filters, sort and selection, and returns them together with the data. Its return value matches the ListContext
shape.
useListController
is used internally by <List>
and <ListBase>
. If your list view uses react-admin components like <Datagrid>
, prefer <ListBase>
to useListController
as it takes care of creating a <ListContext>
.
Usage
useListController
expects a parameters object defining the list sorting, pagination, and filters. It returns an object with the fetched data, and callbacks to modify the list parameters.
Here the code for the post list view above, built with Ant Design:
import { useListController } from 'react-admin';
import { Card, Table, Button } from 'antd';
import {
CheckCircleOutlined,
PlusOutlined,
EditOutlined,
} from '@ant-design/icons';
import { Link } from 'react-router-dom';
const PostList = () => {
const { data, page, total, setPage, isPending } = useListController({
sort: { field: 'published_at', order: 'DESC' },
perPage: 10,
});
const handleTableChange = (pagination) => {
setPage(pagination.current);
};
return (
<>
<div style={{ margin: 10, textAlign: 'right' }}>
<Link to="/posts/create">
<Button icon={<PlusOutlined />}>Create</Button>
</Link>
</div>
<Card bodyStyle={{ padding: '0' }} loading={isPending}>
<Table
size="small"
dataSource={data}
columns={columns}
pagination={{ current: page, pageSize: 10, total }}
onChange={handleTableChange}
/>
</Card>
</>
);
};
const columns = [
{ title: 'Id', dataIndex: 'id', key: 'id' },
{ title: 'Title', dataIndex: 'title', key: 'title' },
{
title: 'Publication date',
dataIndex: 'published_at',
key: 'pub_at',
render: (value) => new Date(value).toLocaleDateString(),
},
{
title: 'Commentable',
dataIndex: 'commentable',
key: 'commentable',
render: (value) => (value ? <CheckCircleOutlined /> : null),
},
{
title: 'Actions',
render: (_, record) => (
<Link to={`/posts/${record.id}`}>
<Button icon={<EditOutlined />}>Edit</Button>
</Link>
),
},
];
export default PostList;
When using react-admin components, it’s common to call useListController()
without parameters, and to put the result in a ListContext
to make it available to the rest of the component tree.
import {
useListController,
ListContextProvider
} from 'react-admin';
const MyList = () => {
const listContext = useListController();
return (
<ListContextProvider value={listContext}>
{children}
</ListContextProvider>
);
};
Parameters
useListController
expects an object as parameter. All keys are optional.
debounce
: Debounce time in ms for the setFilters callbacksdisableAuthentication
: Set to true to allow anonymous access to the listdisableSyncWithLocation
: Set to true to have more than one list per pageexporter
: Exporter functionfilter
: Permanent filter, forced over the user filterfilterDefaultValues
: Default values for the filter formperPage
: Number of results per pagequeryOptions
: React-query options for the useQuery callresource
: Resource name, e.g. ‘posts’ ; defaults to the current resource contextsort
: Current sort value, e.g.{ field: 'published_at', order: 'DESC' }
storeKey
: Key used to differentiate the list from another sharing the same resource, in store managed states
Here are their default values:
import {
useListController,
defaultExporter,
ListContextProvider
} from 'react-admin';
const MyList = ({
debounce = 500,
disableAuthentication = false,
disableSyncWithLocation = false,
exporter = defaultExporter,
filter = undefined,
filterDefaultValues = undefined,
perPage = 10,
queryOptions = undefined,
resource = '',
sort = { field: 'id', order: 'DESC' },
storeKey = undefined,
}) => {
const listContext = useListController({
debounce,
disableAuthentication,
disableSyncWithLocation,
exporter,
filter,
filterDefaultValues,
perPage,
queryOptions,
resource,
sort,
storeKey,
});
return (
<ListContextProvider value={listContext}>
{children}
</ListContextProvider>
);
};
storeKey
To display multiple lists of the same resource and keep distinct store states for each of them (filters, sorting and pagination), specify unique keys with the storeKey
property.
In case no storeKey
is provided, the states will be stored with the following key: ${resource}.listParams
.
Note: Please note that selection state will remain linked to a resource-based key as described here.
If you want to disable the storage of list parameters altogether for a given list, you can use the disableSyncWithLocation
prop.
In the example below, both lists TopPosts
and FlopPosts
use the same resource (‘posts’), but their controller states are stored separately (under the store keys 'top'
and 'flop'
respectively).
import { useListController } from 'react-admin';
const OrderedPostList = ({
storeKey,
sort,
}) => {
const params = useListController({
resource: 'posts',
sort,
storeKey,
});
return (
<div>
<ul style={styles.ul}>
{!params.isPending &&
params.data.map(post => (
<li key={`post_${post.id}`}>
{post.title} - {post.votes} votes
</li>
))}
</ul>
</div>
);
};
const TopPosts = (
<OrderedPostList storeKey="top" sort={{ field: 'votes', order: 'DESC' }} />
);
const FlopPosts = (
<OrderedPostList storeKey="flop" sort={{ field: 'votes', order: 'ASC' }} />
);
You can disable this feature by setting the storeKey
prop to false
. When disabled, parameters will not be persisted in the store.
Return Value
useListController
returns an object with the following keys:
const {
// Data
data, // Array of the list records, e.g. [{ id: 123, title: 'hello world' }, { ... }
total, // Total number of results for the current filters, excluding pagination. Useful to build the pagination controls, e.g. 23

isFetching, // Boolean, true while the data is being fetched, false once the data is fetched
isLoading, // Boolean, true until the data is fetched for the first time
// Pagination

} = useListController();
Using setFilters
to Update Filters
The setFilters
method is used to update the filters. It takes three arguments:
filters
: an object containing the new filter valuesdisplayedFilters
: an object containing the new displayed filtersdebounced
: set to true to debounce the call to setFilters (false by default)
You can use it to update the list filters:
import { useState } from 'react';
import { useListController } from 'react-admin';
const OfficeList = () => {
const { filterValues, setFilters, data, isPending } = useListController({ resource: 'offices' });
const [formValues, setFormValues] = useState(filterValues);
const handleChange = (event) => {
setFormValues(formValues => ({
...formValues,
[event.target.name]: event.target.value
}));
};
const handleSubmit = (event) => {
event.preventDefault();
setFilters(filterFormValues);
};
if (isPending) return <div>Loading...</div>;
return (
<>
<form onSubmit={handleSubmit}>
<input name="country" value={formValues.country} onChange={handleChange} />
<input name="city" value={formValues.city} onChange={handleChange} />
<input name="zipcode" value={formValues.zipcode} onChange={handleChange} />
<input type="submit">Filter</input>
</form>
<ul>
{data.map(record => (
<li key={record.id}>{record.name}</li>
))}
</ul>
</>
);
};
